What must a driver do when entering a roadway from a private drive?

Answer: B — Yield to all traffic on the roadway

When a driver is entering a roadway from a private drive, the correct action is to yield to all traffic on the roadway. This is crucial for ensuring the safety of everyone on the road, including motorists and cyclists already traveling on the public roadway. Yielding means that the driver must slow down or stop if necessary, allowing vehicles and pedestrians to proceed unhindered before entering the thoroughfare. This requirement emphasizes the importance of being courteous and cautious, as a driver pulling onto a busy roadway can create hazardous conditions if they do not give way to existing traffic. It helps prevent accidents that may occur from a driver improperly merging onto the roadway without considering the presence and right-of-way of other users. Drivers must always prioritize the safety of others and adhere to traffic laws designed to maintain order and prevent collisions when transitioning from a private space to a public road.
